Introducing the DARHNIGHT Green Led from Agrolite. This 20W bulb will prevent your crops from "flashing". You can work on your crops during the hours of darkness thanks to its green filter.
During the flowering period, it's essential to respect the night-time photoperiod for your crops. During this period, your plants must be in absolute darkness. If they receive light for even a few minutes, they risk a shock of light that could result in delayed vegetative growth and stagnation.
This lamp gives a green light that is not perceptible to the plants. So you can work on your crops at any time, or simply contemplate them.
